The Suffolk Traction Company is a former streetcar system in Suffolk County, New York. It operated primarily between Patchogue and Holtsville,
but also included a route that served Blue Point, Bayport, and Sayville.

The four current roads that originally carried the trolley line between
Patchogue and Holtsville are South Ocean Avenue, North Ocean Avenue,
and what today is Old North Ocean Avenue. The PD Tower at Patchogue Railroad Station served as a control tower for both the Long Island Railroad
and the trolleys. Traction Boulevard (also known as Suffolk Traction Boulevard)
continued the line, which crossed over the southeast corner of Canaan Lake
and headed in a northwesterly direction. North of the Patchogue Highlands area, the paved road became a dirt trail and carried the former
ROW towards Holtsville Station. The trolleys that
used the road were storage battery cars that ran down the center of the
street.
